JACKETED CASVING.

Application filed April 23., 1925. Serial No. 25,338.

.This invention relates tor improvements in casings t'or the rotary or rotary and reciprocating cylinders ot dyein. bleaching, soapino. scouring, and Washing machines. j

The primary object et the invention is to provide a casing suitable Yfor use as the outer container for the rotary or rotary and ileciprocating cylinders ot dyeing, bleaching, soaping` scouring. and Washing machines nonY in common use in knitting mills, dye houses, bleacheries, and laundries.

A lurther object ot the invention is to provide insulating,r means to permit the contents ot the casing to be economically heated and also for controlling the concentration, acidity, and alkalinity or chemical aspect of the same.

Other objects and advantages ot' the invention will be apparent: during the course ot the 'tolloiving description. Y

This invention embodies further nnprovenients in the art to which it relates, and more particularly in connection with Patent No. 1,391,712, issued to D.B.Becker, on September. 27, 1221. y

ln the accompanying drawings forming a part otthis specification and in which like numerals are employed toA designate like parts throughout the same,

F ignre 1 is a transverse, vertical sectional view of one improved form ot casing embodying this invention,

Figure 2 is a longitudinal, vertical sectional view ot the casing shown in Fig. 1,

Figure 3 is a transverse. vertical sectional view otl a slightly modied form ot' casing embodying this invention,

F igure 4 is a 'fragmentary vertical sectional view oit a further modiiied form ot casing showing structure which will permit the drawing of ajvacuum Within a casing, and

Figure 5 is a fragmentary vertical, longitudinal sectional view ot the 'form ot casing shown in Fig. Il.

ln the drawings, wherein tor the purpose ot illustration is shown a preferred embodiment ol this invention, the numeral 5, in Figs. 1 to 3 inclusive, designates the standards employed t'or supporting the casing. In these same figures the standards 5 are illustrated as having mounted thereupon the semi-cylindrically-shaped Wooden or other suitable protector shell 6 which is formed from Aa extending strips.

in the form of the invention shown in Vltigs. 1 and 2, the Wooden protector shell 6 rhas received therein the metallic cylinder 7 having the door 8 hinged thereto at 9 for closing the opening 10. Surrounding the portion ol1 the cylinder 7 Within the Wooden protector shell (S is a layer ot' insulating material 11 which is slightly spaced from the metallic cylinder 7 to t'orm a steam pressure jacket 12 therebetween. The layer ot' insulating` material 11 is extended, as at 11n to cover the upper portion of the cylinder 7. Y rthe hingedly mounted cover 8 is also provided With an insulating covering 13, as best illustrated in Fig. 1. Fig. 2 shows the closed ends oli the metallic cylinder 7 covered by layers ot insulating material 14 and the steam jacket 12 may also cove-r they closed ends ot' the cylinder. The end Walls ot tie metallic cylinder 7 and their insulatingv lavers 14,- and also the steam pressure jacke-te when used on the ends are formed with axially positioned openings 15 adapted tor receiving stuliing boxes, not shown, which are intended to support the journals oit' a rotatable drum, or the like. n j* The lower Wall of the cylinder 7 is formed with a drain 16 thru which the bleaching, sOaping. scouring, dyeing'7 or Washing bath may be removed from the cylinder. The end Walls ot the. cylinder 7 and the insulating layers leland end steam pressure jacket when used are formed with openings 17 which are employed torpermitting the entrance and eXit oit' imperferate or perforated heating coils or pipes, it' the same are desired for raising the temperature of the bath to be placed in the cylinder. It such heatingl means is not desired, these openings 17 may be closed or plugged in any dc-sired manner.

The periphery oit the metallic cylinder 7, i. e., the portion Within the steam pressure jacket 12, is provided With a plurality of spirally extending ribs forming condensate ducts 18. Vln Fig. 2 the end layers l-il of insulating material are shown as being provided With an inlet 19 and an outlet 2O by means of which steam may be circulated thru the pressure jacket 12.
